Now that Drupal 8.0.0-beta1 is out, and the headless Drupal craze is in full-swing, the Drupal St. Louis meetup this month will focus on using Drupal 8 with AngularJS to build a demo pizza ordering app. (The meetup is on Thurs. Oct. 23, starting at 6:30 p.m.; see even more info in this Zero to Drupal post).
We'll be hacking away and seeing how far we can get, and hopefully we'll be able to leave with at least an MVP-quality product! I'll be at the event, mostly helping people get a Drupal 8 development environment up and running. For some, this alone will hopefully be a huge help, and maybe motivation to adopt Drupal 8 more quickly!
If you're in or around the St. Louis area, consider joining us; especially if you would like to learn something about either Drupal 8 or AngularJS!
P.S. To those who have been emailing: the rest of the Apache Solr search series is coming, it's just been postponed while I've started a new job at Acquia, and had a new baby!
